Campanula plant named ‘PKMTAK3’

ABSTRACT

A new and distinct cultivar of  Campanula  plant named ‘PKMTAK3’, characterized by its compact plant habit; dense and bushy plant form; vigorous growth habit; and large, purple flowers.

Latin name of genus and species of the plant claimed: Campanulatakesimana.

Variety denomination: ‘PKMTAK3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCampanula plant, botanically known as Campanula takesimana, commonlyknown as Bellflower, and hereinafter referred to by the name ‘PKMTAK3’.

The new Campanula, ‘PKMTAK3’, is a product of a planned breeding programconducted by the inventor, Christian Hald Madsen, in Søhus, Denmark. Thenew Campanula originated from a cross made by the inventor in March 2009between a proprietary selection of Campanula takesimana designated21.01.0083 (breeder reference, unpatented) as the female parent and aproprietary selection of Campanula punctata designated 39.00.3010(breeder reference, unpatented) as the male parent. The new Campanula‘PKMTAK3’ was discovered and selected by the inventor as a singleflowering plant within the progeny of the stated cross in a controlledenvironment in Søhus, Denmark. The inventor selected ‘PKMTAK3’ on thebasis of its compact plant habit and purple flowers.

Asexual reproduction of the new Campanula cultivar by terminal cuttingshas demonstrated that the combination of characteristics as hereindisclosed for the new cultivar are firmly fixed and retained throughsuccessive generations of asexual reproduction. The new cultivarreproduces true-to-type.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘PKMTAK3’. These characteristics incombination distinguish ‘PKMTAK3’ as a new and distinct cultivar:

-   -   1. Compact plant habit;    -   2. Dense and bushy plant form, mainly due to short, upright and        stiff stems;    -   3. Strong peduncles in greyed-purple and green color;    -   4. Purple and white flowers.

Plants of the cultivar ‘PKMTAK3’ can be compared to the Campanulatakesimana cultivar ‘PKMTAK2’ (U.S. plant patent application Ser. No.13/507,208). In side-by-side comparisons conducted by the inventor inStige, Denmark, plants of the instant cultivar ‘PKMTAK3’ and plants ofthe cultivar ‘PKMTAK2’ differ in the following characteristics:

-   -   1. Plants of the ‘PKMTAK3’ produce flowers with a deep purple        color whereas plants of ‘PKMTAK2’ produce light red-purple        flowers.    -   2. Plants of ‘PKMTAK3’ have greyed-purple peduncles whereas        plants of ‘PKMTAK2’ have green peduncles.

DETAILED BOTANICAL DESCRIPTION

The new Campanula ‘PKMTAK3’ has not been observed under all possibleenvironmental conditions. The phenotype of the new cultivar may varywith variations in environment such as temperature, light intensity, daylength, and fertility level without any variance in genotype.

The aforementioned photographs, together with the followingobservations, measurements and values describe plants of the newCampanula ‘PKMTAK3’ as grown under greenhouse conditions. No growthretardants were used.

The age of the ‘PKMTAK3’ plants described is about 10 months aftercutting. Color references are made to The Royal Horticultural SocietyColour Chart (R.H.S.), 5^(th) edition, except where general colors ofordinary significance are used.
